(HealthDay News) -- A breast biopsy involves removing a sample of breast tissue or fluid to test for the presence of cancerous cells.

The U.S. National Library of Medicine says here's what you can expect from a non-surgical needle biopsy:

  • You will lay on your side or sit on an exam table.
  • A health care provider will clean the biopsy site and inject it with an anesthetic, so you won't feel pain during the procedure.
  • When the area is numb, the health care provider will insert a needle into the site and remove a sample of tissue or fluid.
  • You may feel some pressure as the sample is being withdrawn.
  • Pressure will be applied to the biopsy site until any bleeding stops. A sterile bandage is then applied to help prevent any additional bleeding.
